Overview
The TL431CLPRAG is a three-terminal programmable shunt regulator diode manufactured by onsemi. It operates as a low temperature coefficient Zener reference, adjustable from Vref to 36 V using two external resistors. The device features a wide operating current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 Ω. It offers a reference input voltage tolerance of ±2.2% and an equivalent full-range temperature coefficient of 50 ppm/°C typical. The component is housed in a TO-92 package (LP suffix) and supports an ambient temperature range of 0 °C to +70 °C.
Feature Summary
- Programmable output voltage capability up to 36 V via external resistor divider
- Temperature compensated operation across the rated ambient temperature range
- Low dynamic output impedance for stable regulation performance
- RoHS compliant construction utilizing lead-free and halogen-free materials
Applications
- Digital voltmeters requiring precise voltage references
- Power supply feedback control circuits
- Op amp circuitry serving as positive or negative voltage references
- Constant current sources and sinks
Procurement Notes
Verify the specific ordering suffix CLPRAG against the manufacturer's official documentation to confirm the exact shipping configuration and package style. Confirm that the 0 °C to +70 °C operating temperature range aligns with the thermal requirements of the target application environment before finalizing procurement decisions.
Selection Notes
Select this component when a standard 2.5 V reference is insufficient and a higher programmable voltage is required. The TO-92 package is suitable for through-hole mounting applications. Ensure the design accommodates the specified 2.2% initial accuracy and the 50 ppm/°C temperature coefficient for the intended operating conditions.
Part Context
This device belongs to the TL431 family of programmable precision references produced by onsemi. The family includes variants with different tolerances and temperature ranges, such as the TL431A and TL431B series. The CLPRAG designation specifically indicates the C-series tolerance level packaged in the TO-92 form factor with tape and reel shipping.
Replacement Considerations
Compatible substitutes include TL431ACDG, TL431BCDG, and TL431CDG. Verify pinout compatibility and electrical specifications against the original datasheet before implementation.
